It will NOT be spectacular, and it is definitely not a great comet, BUT, it is expected to be naked eye visible and it will be — WITHOUT FAIL — appear the week before Christmas 2018. It is Periodic Comet with a 5.4 year orbital period. So, it is a well known comet and one that is not going to fizzle away as did MY comet ISON in 2013.
This is just the initial heads-up. I just found out about it today. I will keep you posted. Promise.
Just mark it on your calendar. December 16, 2018 — COMET!
Exciting. We haven’t had a decent naked eye visible comet in DECADES!
